TACT, one of the first companies to offer sophisticated room correction, now adds Dynamic Room Correction. It adjusts the equalization to provide optimum response as you change the setting of the volume control. Older audiophiles might think of it as a sophisticated loudness control. The system will be built into the company's two-channel RCS 2.2 XP processor first, but will ultimately find its way into a redesigned surround pre-pro (now on hold pending the arrival of HDMI 1.3). TACT has also improved its user interface, making it faster to arrive at an optimum target curve.
